object is carried through time to new users, currentusers. In different contexts it might be different per-ceptions of what authenticity is, and what we wantto achieve is a certain trust in the user that this is thedigital object that was once created with this identi-ty, because the identity is dependent on the creator.'

The Austrian National Library's Max Kaiser, poin-

ted out three different types of digital object: `Whenwe receive the object we have to decide what part ofit is to be preserved.Then we have to submit it toour archives and begin recording the changes thathave to be made to it ­ migration and other things.We have to record rights issues and then, based onthis complicated information package, we have todecide how we can disseminate it to our users.'

Professor Duranti put it: `So, in fact, the grave re-

sponsibility for future preservation is with the creator.The creator has to make sure the object is identifiable;that it has metadata to ensure its integrity can beproved; that it can be seen, with access privilege; thatsort of thing.We therefore should also look atmethods that should be used by the creator to gene-rate the objects properly for future preservation.'

She said that the InterPARES project had created

two different sets of requirements for authenticity,one for the creator and another for the preserver.

Other members thought perhaps three sets of

requirements were needed: `ingest', `preservation' and`dissemination' was Nils Brübach's model.The groupdiscussed the role of the preserver as mediator between the creator and user.The preserver's taskwas to create records, too, it was suggested, recordssuch as protocols describing what had been lost oradded in the preserving process, giving authenticityto what was left. Once these had been satisfied andan audit trail tracking process was in place then authenticity could be presumed.

In his summing up, Hans Hofman said the group

had agreed that authenticity was not a static thingbut had to be approached from the contextual pointof view. He added: `We did not come up with a lotof criteria, but at least one is that an authentic objectis what it purports to be, and there are different play-ers: the creators, the preservers and the users, and allhave their own views that influence the way we dealwith authenticity.'
